@Ceili,
There are 3 types of rural property in Mexico. Private, ejidos and communal.
Private is, well, private. A person or a corporation owns the land. Private ownership is limited to 200 has. per person. But there is land leasing, too.
Ejidos, a big plot is given to an ejido -an association of peasants-; the ejido decides how to work it (usually each one has a plot and they all sell the crop together). If an ejidatario dies, his son inherits the membership (not his daughter, or his wife, or his siblings). The ejido is the owner of the land, and can only sell it or lease it (or parts of it) if the Assembly decides to do so.
Comuneros, a plot is owned by a community, usually an indigenous community, and is worked collectively.
Some ejidos are big, some are small. Some are very productive, some are not. Most of them come from land redistribution after the Revolution.
